With plenty of two-income highly educated families, the D.C. region already has a reputation as one of the most affluent in the country. But the area is fast emerging as a home to the truly rich as well.

High-end luxury retailers are responding. Brands such as Aston Martin are expanding their operations into the area — betting, for instance, that there will be plenty of customers who can afford the $280,000 sports car James Bond drives in the movies. Nearby in Tysons, a Saint Laurent store and the high-end electric car maker Tesla are also set to open their doors.
